    Abstract:
    Massive pulmonary hemorrhage, although rare, is a potentially life-threatening complications during heart surgery. We herein present 1 such case successfully treated by selective bronchial occlusion using an Endobronchial Watanabe Spigot (EWS). The 82-year-old female underwent mitral valve replacement, tricuspid annuloplasty, and maze procedure. An hour and a half after cessation of cardiopulmonary bypass, the patient suffered a massive pulmonary hemorrhage. A subsequent bronchoscopy identified the hemorrhage site at the right middle lobe bronchus (B5b), and an EWS was then selectively deployed into this bronchus to block the hemorrhage. The following day, bronchial arterial embolization was performed, enabling the removal of the spigot on the next day. The patient's respiratory condition gradually improved, allowing for extubation on the 21st postoperative day. By preventing bleeding into neighboring bronchi, which, in turn, avoids the risk of exacerbating hypoxia, bronchial occlusion with EWSs is highly effective in managing massive pulmonary hemorrhage during heart surgery.
